solving numerically the frequency and mode of the problem using roop

[Jslim_104115]

Dear Masters,

I would like to simplify the equation by repeating the program of the vibration analysis no repetition below using for statements, etc.
The process I'm trying to do is vibration analysis repeat
I want to draw the simplified graphs together on one graph, but it is not easy.
Finally, I want to draw a final graph superimposed by adding five eigenfunctions. I need the help of masters.
My version is Prime 6.0.

You are using i as subscript but it should be vector index.
